2 Claims.

which a preferred form of theinvention is illustrated.

In the drawings:

Fig. 1 is a front elevational view of a device embodying the invention and with the front portion of the casing-members thereof removed in order better to disclose the interior mechanism.

Fig. 2 is an end elevational view of the right end of the machine in Fig. 1; and

Fig. 3 is a substantially corresponding elevational view of the left end of the machine.

As shown in the drawings, a frame I is fitted with bearings 2, 3, 4, to support a horizontally extending shaft 5 to which is rigidly secured a drum 6. The upper half portion of this drum is shown enclosed within a semi-cylindrical casing member 1 which at T is shown pivotally mounted on the frame at the rear edge thereof and is at the top fitted with a hopper 8.

As best shown in Fig. 2, a lower casing member 9 is hung on a hinge lb of the frame directly below the hinge I of the upper casing member, together therewith completely to encompass the drum 6. Suitable means, such as a slide I I, engages a perforation of the frame at the forward edge of the casing member 9 and it extends under the edge of the casing member to maintain the latter in the elevated position shown in full outline in Fig. 2. This slide is shown fitted with a handle l3 by means of which it may be retracted to release the casing member for opening movement.

Returning now to Fig. 1, it is noticed that a fan I5 is mounted for rotation on the shaft 5 and the hub l6 of this fan is shown extended to form a support for a pulley l1, which is rigidly fixed in position thereon. The hub of the fan is held against axial displacement on the shaft between the hub l8 of the drum 6 and the bearing 3, and it is connected for rotation by means of a belt l9 extending to the pulley 20 of an electric motor 2|.

A second pulley 24 is rigidly mounted on the shaft 5 and it is by means of a belt 25 connected for rotation to a pulley 26 of the motor;

2|. By means of driving connections, such as just described, it is seen that the drum may be rotatable at a fixed speed; whereas the speed of rotation of the fan may be varied to suit operat-.

ing conditions. In order to facilitate and expedite such change of fan speed, stepped pulleys may be employed as indicated in the drawings.

In the positionindicated in full outline in Fig. 2, the machine is adjusted to pick and renovate cotton or kapok filling material, which is fed into the hopper and by the drum 6 carried into the fan I 5 to be discharged through a chute 26. The drum is, for this purpose, shown fitted with a series of equidistantly placed bars 21, which are set on edge and the outer edges thereof are notched in order to provide continuous rows of sharp teeth. It is important to note that these bars are somewhat inclined on the drum in order to 'direct the picked material into the rapidly rotating fan. I5 and that the centrifugal force exerted by the revolving fan creates sufficient suction to draw the picked material fromthe drum through the fan to the chute 26. The lower case member 9 is made from foraminous material in order to permit dust, grit and other foreign matters to drop through this; member as the material is carried along the inner surface of the casing. The materials in this manner discharged from the casing drop on to an inclined tray 29, gradually by gravity to be discharged into a suitable waste receptacle 30.

The above described arrangement of the machine is found most practical and eflicient in connection with cotton and kapok material, but it is found that, where hair filler is to be renovated, the fan cannot be depended upon to draw the picked hair away from the drum, in addition to which it is found that the hair becomes tightly matted between the bars of the drum and the inner surfaces of the drum casing. For this reason, it is found necessary to discontinue the use of the fan which in any suitable manner, as by disconnecting the fan belt I9, is allowed to come to a stop. It also becomes necessary toswing the lower casing member away from the drum so as to release the picked hair which accumulates between the drum and its casing, and permit it to drop directly on to the tray 29. The latter is in the drawings shown pivotally hung at 3| and the rear end of the tray is shown maintained in elevated position by means of a latch 32. The latter is mounted on a pivot 33 and it is fitted with a handle 34 by means of which the latch may be swung out of the way so as to perspring held in mit the tray to drop into the lowered position indicated in dotted outline in Fig. 2 against a crossbar I of the frame. The casing member 9 may then be swung into the position indicated at 9 to permit the tray 29 to be returned to its elevated position. When this operation is completed, the frame member 9 is free to drop into the position indicated at 9' in Fig. 2.

When the machine is in this manner adjusted, it is found that the picked hair material is expelled from the hopper and thrown directly on to the tray 29 to be by gravity discharged therefrom into a suitable receptacle, such asv the container 30.

It was above statedthat the belt l9 can be disconnected in order to bring the fan to a standstill during rotations of the drum; Such disconnection may be effected by merely withdrawing the the belt from the pulley or it may be more conveniently accomplished by providing a suitable belt tightener' such as indicated in Fig. 3 to consist of a lever 36, which is hung to swing ona stud 31 of themachineframe andJfitted at.

the inner end with a pulley 38. The latter is wide. enough to span the entire width of the pulleys IT and 20. The lever is, by means of a spring 35 held yieldingly pressed. against the belt as required for transmitting rotation from the motor to the fan. When it'is desired to disconnect-the fan from themotor' it is merely required to swing the lever 33 on its pivot in clockwise direction, thereby to withdraw the pulley 38 from. the belt and so to. permit the belt to hang loosely suspendedfrom the pulley H'. A hand lever- 39 is pivotally hung on the machine frame above the rear endi36 of the lever 36 for manual tilting movement in counter-clockwise direction to cause the inner end3l thereof to depress the rear end of the lever 38against the tension of the spring 35; and somaterially to facilitate the operation of withdrawing the pulley 3.8- from thebelt; This hand leveris' by the tension of; the this-tilted positionand so may be depended upon tomaintainzthecpulley lever 35 in its withdrawn position until rotation of the fan is again required. I claim:

1'. A mattressfiller renovating machine comprising, a-frame, a cylindrical casing" horizontally divided into an upperand a lower half-portion,v

both hingedly supported on said frame at the rear edge thereof for upward and downward swinging movement respectively, a tray below the casing pivotally secured to the front edge of the frame for vertical swinging movement from a forwardly inclined position downwardly to a rearwardly inclined position, means for maintaining said tray locked in its forwardly inclined position on the. frame, said means being; manually operable to release the tray for downward movement on its pivot into position to clear the lower casing portion for downward and rearward swinging movement beyond the rear edge of the tray, return movement of the tray to its forwardly tilted position providing a stop for return movement of said lower casing portion.

2. A mattress filler renovating machine comprising, a frame, a cylindrical casing horizontally divided into an upper and a lower half-portion,

both hingedly supported on said frame at the rear edge thereof, a shaft axially extending through said casing, apicking drumrigid on said shaft, a fan rotatable on the shaft, means for independently rotating said shaft and the said fan, a tray below the casing pivotally secured to the front edge of the frame for vertical swinging'movement from a forwardly inclined position downwardly to a rearwardly inclined position, means for maintaining said tray locked in its forwardly inclined position on the frame, said means being manually operable to release the tray for downward movement on its pivot intoposition to clear the lower casing portion for downward and rearward swinging movement beyond the rear edge of the-tray, return movement ofthetray to its forwardly tilted position providing a stop for return movement of said lower easing portion.
